Abstract

Ein Diaphragma für alkalische Elektrolysen, insbesond­ re für die alkalische Wasserelektrolyse, mit einer feinporö­ sen, insbesondere keramischen Schicht, die vorzugsweise von einem gerüstgehenden Träger oder Netz gestützt wird und an der die Elektroden sandwichartig anliegen, wird mit über die Fläche verteilten, in die feinporöse Schicht integrier­ ten gröberen Körnern ein- oder beidseitig versehen, die aus der Oberfläche vorragen und trotz anliegender Elektrode für einen gewissen Minimalabstand zwischen Diaphragma und Elektrode sorgen, so daß durch unvermeidbare Korrosions­ phänomene innerhalb der Apparatur bedingte Abscheidun­ gen auf den Elektroden nicht in das Diaphragma hineinwach­ sen können. Diese gröberen Körner von etwa 10 - 250µm werden bei der Herstellung des Diaphragmas vor dem Sintern in dünner verteilung auf die Oberfläche gebracht und unter geringer Druckanwendung in die Oberfläche soweit hineingetrieben, daß sie noppenartig daraus vorstehen.
